It's very pleasing to see that exploitation of geothermal energy continues to grow. It is the only type of energy with absolutely no downside.

It is reliable, with no reliance on the sun to be shining or the wind to be blowing. No practical limit (other than its limited geographical availability, with current technology). No harmful side-effects such harmful emissions (mercury, sulfuric acid, CO2, etc.) or bird kills (windmill blades) or mining operations (coal, uranium) or fish spawning impediments, etc. And, even though it does have some initial capital investment that can be significant, compared to that of nuclear, it is miniscule.

Geothermal energy is just about as good as it gets when it comes to extracting energy from our environment. I hope its use continues to be advanced and at a much more rapid rate.

Is global warming the threat it is perported to be? If so why aren't we making use of Yellowstone for geothermal energy? ... and doing it in such a way that it is barely visible so tourists can still enjoy the park as they do now.

I once read an article that said, making use of Yellowstone for geothermal is estimated to be able to produce 70 billion watts of power. Enough to replace 35 2GW coal fired power plants.

We have recently found a lot of natural gas, and are producing more oil than ever before. But these are resources that decrease every year until they run out. If we had found and used these resources at the time the declaration of independence was signed, these wells would be dry by now. Yellowstone could continue to give us power until the sun becomes a red giant and engulfs the earth.

Yeah!
The downside, is that MOST Utahans don’t believe or support renewable Green Energy so they turn a blind eye to it.
California believes in it, will pay for it, so the power companies end up sending it there – leaving Utah with it’s dirty, antiquated coal.

FYI – Geo-Thermal doesn’t just have to be on a giant scale. I had a Geo-Thermal heat pump installed in our house in Seattle.
Heat in the Winter, Cool in the Summer --- I paid $18 - $27 a month for Heating and Cooling.

The technology is here, it’s now.

There are downsides to geothermal.

You need water to pump underground to retrieve the heat.

The water, returning as hot water or steam, contains minerals and gases which are potential air, water, and solid waste pollution. These materials also make the water/steam more corrosive than the high-purity boiler feed water used in most thermal power plants. The increased corrosivity requires that expensive turbine parts be replaced more frequently.

Usually the subsurface must be fracked to allow water from the injection well to flow to the recovery well. The underground formation often degrades with time and energy yields decrease, just like with oil and gas wells.

I don’t know anyone who is opposed to developing REAL alternative energy, Its just that most people know it isn’t viable yet! As long as the government is in the energy business, it will never be viable! If you doubt that think about Solyndra!

@Mounta(i)nman
your absolutely right one business gone bad means an entire industry is worthless. Shall we apply this same reasoning to all industries or just those that you appose?
